Description
Technical field
The present invention relates to field of feed, and in particular to the pig feed of Zn-ef ficiency utilization rate in a kind of raising grain trough
Formula.
Background technology
Zinc is trace element necessary to animal body, and discovery has zinc in more than 200 kinds of enzyme needed for being metabolized in vivo
In the presence of.Zinc deficiency or malabsorption, can influence the protein metabolism of pig and cause animal feed intake to reduce in daily ration, can trigger
Diarrhoea, undergrowth, per gain weight food consumption increase, skeleton development various situations hairs for being unfavorable for breeding production such as unsound
It is raw.The main path of current animal feeding supplement zinc is the zinc in feed needed for extra addition, and major part is based on inorganic zinc.
Inorganic zinc absorption rate is relatively low, the zinc of excessive addition in pig feed, not only increases production cost but also can increase excrement
Just the deposition of middle zinc, environmental pollution is caused to ecological environment.In livestock and poultry cultivation production the discharge of the trace element such as zinc gradually into
How one of problem all urgently to be resolved hurrily for puzzlement agricultural sustainable development, improve the biological utilisation of zinc in feedstuff body
Rate has important practical significance to livestock and poultry cultivation production.
People meet growth of animals or poultry needs and but ignore for feed simply by a large amount of zinc of external source addition for a long time
The utilization of body zinc in raw material.The Zn content in feed body is not accounted for when feed formulation is carried out, and be with the addition of excessive
Zinc, and then the actual content of zinc in feed is caused beyond needed for the growth of animal.Excessive zinc can not only be inhaled by livestock and poultry
Receipts excrete pollution environment on the contrary, will also cause the waste of resource to increased production cost.Grain trough raw material is as barley, jade
Contain a certain amount of body Zn-ef ficiency in rice, wheat, oat etc., but animal to its utilization rate than relatively low, mainly due to
The SNSP such as the beta glucan containing higher level, xylan and cellulose in grain trough raw material, nonruminant digestion
Road due to lack degraded SNSP enzyme or enteric microorganism produce the quantity of these enzymes few and can not to its digestibility and utilization,
Therefore SNSP micro- with zinc etc. will form compound and reduce utilization rate of the animal to trace element.Additionally,
SNSP can also increase enteron aisle chyme viscosity, hinder feed nutrient and mix with the digestive ferment of digestive secretion and reduce nutrient
Digestibility, while also influence to have digested nutrient and transporting and absorbing in alimentary canal.
ANFs enzyme common at present has phytase, non-starch polysaccharide enzyme etc., and they are in feed industry
It is widely used, the ANFs in feedstuff can be eliminated so as to improve Nutrients Digestion absorptivity.Enzyme is being improved
While Nutrients Digestion, if can be discharged the trace element in feedstuff body, the research of current this respect is very few.
The present invention with feedstuffs such as general grain feeds as research object, by adding the anti-battalion of a certain amount of ANFs in feed
Factor enzyme, and combination in-vitro simulated digestion trial and animal vivo test are supported, obtaining one kind can improve sheet in grain trough raw material
The formula for pig forage of body zinc utilization ratio.This is the emission reduction depth of ANFs enzyme scientific application and trace element in Animal nutrition
Enter research to lay the foundation.For simultaneously for greenization husbandry sector, it is possible to reduce the row of the element such as zinc during animal-breeding
Put, and then preserve the ecological environment, with popularization and application value well.
The content of the invention
Problem to be solved by this invention is to provide a kind of pig feed for improving zinc utilization ratio in grain trough raw material and matches somebody with somebody

0.5mL chloramphenicol ethanol solution (0.5mg/mL ethanol), 39 DEG C of water-bath digestion 5h are simultaneously constantly slowly stirred, and simulation feed is in stomach
Digestion process.
(2) after simulation digestion gastric digestion process terminates in small intestine, it is firstly added 10mL phosphate buffers (0.2mol
L-1, pH 6.8) and 5mL 0.6molL-1NaOH solution, then pH is adjusted to 6.8 with the NaOH of 1molL-1, it is eventually adding
1mL trypsin solutions, 39 DEG C of water-baths continue to digest 8h, and magnetic stirring apparatus is constantly slowly stirred, and simulation feed is in enteral digestion
Process.After digestion terminates, digestion product is carried out into suction filtration, cross 0.45um filter membranes, collect the supernatant after suction filtration.
(3) be placed in supernatant in 250mL tool plug conical flasks by supernatant Wet, adds 25mL mixed acid (nitric acid：
Perchloric acid=4:1, volume ratio), after soaked overnight, heating is cleared up to digestion solution in water white transparency or showing slightly yellow, cooling,
With 1% dilute nitric acid solution constant volume to 50mL, while making blank, (the wet digesting rear constant volume of mixed acid for being not added with sample is arrived
50mL)。
(4) determination of trace elements refers to GB GB/T 13885-2003.Respectively by the standard solution of each element, examination
Agent blank solution and measurement sample liquid import Atomic Absorption Spectrometer and are measured, and element in sample is checked according to standard curve
Concentration.Each sample is surveyed 3 times, is averaged.
2nd, result and analysis
Soluble state Zn-ef ficiency changes of contents in grain trough, as shown in table 1.
Soluble state Zn-ef ficiency content (unit in grain trough after the ANFs ferment treatment of table 1：mg/kg)
As can be seen that the soluble state Zn content of ANFs ferment treatment group barley improves than control group in result of the test
40.71%, ANFs ferment treatment group corn soluble state Zn content improves 18.26%, ANFs enzyme than control group
Treatment group wheat soluble state Zn content improves 32.74% compared with control group, and ANFs ferment treatment group oat soluble state zinc contains
Amount improves 23.21% compared with control group.
3rd, conclusion (of pressure testing)
This experiment illustrates that addition ANFs ferment treatment can significantly improve Zn-ef ficiency release efficiency in grain trough,
So as to can in theory prove effectiveness of the invention.
Swine rearing is tested
Tested by swine rearing, it was demonstrated that formula for pig forage of the present invention is to growth of animal performance and the shadow of Zn-ef ficiency utilization ratio
Ring.
1st, test method

110kg) 3 stages.
1 before on-test, the 25th day (20~35kg), the 74th day (35~70kg) and off-test (70~110kg)
It 21:00 fasting, next day 09:00 carries out weighing on an empty stomach in units of repetition to all test pigs.
1.2 slaughter experiments
1.2.1 Zn-ef ficiency content in organizing
After butchering, left intrahepatic leaf, left cortex renis, myocardium of left ventricle, left side spleen and longissimus dorsi muscle are taken, be sub-packed in sample sack
In, then -80 DEG C of preservations determine Zn-ef ficiency content in each tissue.
1.2.2 Zn-ef ficiency utilization rate
From on-test, every 10 days, in units of repetition, uniform collection excrement.Feed is sampled simultaneously, is adopted
The feed and excrement of collection after treatment, sealing preserve.Use Instrument measuring Mineral Concentrations.
